An engineer who had an arms factory behind his garage was jailed for 10 years yesterday at Belfast Crown Court. Last September, Denis Lindop (48) pleaded guilty to the unauthorised manufacture of submachine guns and having a large quantity of arms, ammunition and primers with intent to endanger life. The haul, which included 68 guns and 11,000 rounds of ammunition, was found during an RUC search of Lindop's home in Holywood, Co Down.
